Conventional lubricants are produced out of petroleum, a commodity that gets more and more expensive. When used, they usually end up at the soil or water, causing irreversible contamination, as nature lacks of microorganisms which can degrade it. Green lubricants, on the other hand, disappear naturally out of microbic action as any other organic fat.
The group that's investigating this is focused in characterizing the oil in each cultivation, finding new extraction processes and also characterizing the wax remaining when the seed is compacted. Other aspects considered are how to improve the lubricant ability of the wax lowering its solidification point.
